Catalog Number: 107-11
Source: Escherichia coli.
Molecular Weight: Approximately 34 KDa, a single non-glycosylated fusion protein containing the extracellular domain of human ErbB3 fragment ( 190 amino acids, Met1-Cys190 ).
Quantity: 1000 μg
Purity: >95% by SDS-PAGE and HPLC analyses.
Biological Activity: Fully biologically active. Measured by its ability to postpone tumor emerge time of spontaneous breast cancer in FVB/N transgenic mice and inhibit the development of tumor, effectively inhibit the growth of in situ transplanted breast cancer in FVB/N transgenic mice.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation: A white, semitransparent suspension, the normal content of each vial is 1 mg of rhErbB3-f, 1mg aluminum hydroxide and small amount of arginine, sodium chloride, sodium phosphate, and potassium phosphate.
Endotoxin: Less than 1EU/μg of rHuErbB3-f as determined by LAL method.
Dilution: It is recommended that sterile phosphate-buffered saline containing 1mg aluminum hydroxide be added to the vial to prepare a stock solution.
Storage: This liquid suspension is stable for several months at 0-4°C, but should be kept at -20°C for long term storage. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
Usage: This material is offered by Shanghai PrimeGene Bio-Tech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
